[Comparison of endotracheal tube cuff pressure changes using air versus nitrous oxide in anesthetic gases during laparoscopic abdominal surgeries].

Background And Objectives: The purpose of this study was to compare the endotracheal tube cuff pressure changes during laparoscopic surgeries using air versus nitrous-oxide in anesthetic gas mixture; and to observe the incidences of postoperative sore throat, hoarseness and dysphagia.

Methods: Total 100 patients scheduled for elective laparoscopic abdominal surgery were allocated into two groups. Group A ( = 50) received air while Group N ( = 50) received nitrous-oxide in anesthetic gas mixture.
